The angle-adjusting vehicular headlights 100 (hereinafter invention) comprises a housing 200, a swivel bracket 220, a distance checker 230, a tilt mechanism, a controller 262, and a headlight socket 240. The invention 100 may change an elevation angle 300 of a headlight 950 responsive to a determination by the controller 262 that an inclination angle of a vehicle has changed. As non-limiting examples, the inclination angle may have changed due to a cargo load that has been placed into the vehicle thus compressing the vehicle suspension or the inclination angle may have changed due to the cargo load being removed from the vehicle and the resulting decompression of the vehicle suspension.

The housing 200 may be an outermost enclosure for the headlight 950. The housing 200 may couple to the vehicle. The orientation of the housing 200 may remain fixed relative to the vehicle as the cargo load within the vehicle changes. This may indicate that the elevation angle 300 of the headlight 950 mounted within the housing 200 would change as the inclination angle of the vehicle changes if the invention 100 was not present or not working. The housing 200 may comprise a right motor mount 204 and a left motor mount 202. The right motor mount 204 and the left motor mount 202 may be projections within the housing 200 located on alternate lateral sides of the housing 200. A right motor 276 may couple to the right motor mount 204 and a left motor 266 may couple to the left motor mount 202.

The swivel bracket 220 may be a pivoting bracket located within the housing 200. The swivel bracket 220 may be pivotably coupled to the housing 200 via a right pivot 224 and a left pivot 222. The headlight 950 may removably couple to the front of the swivel bracket 220 such that the elevation angle 300 of the headlight 950 is determined by the swivel bracket 220. The swivel bracket 220 may pivot to change the elevation angle 300 of the headlight 950 relative to the housing 200.

The distance checker 230 may determine a height 320 of the housing 200 above ground 910. The distance checker 230 may be coupled to the housing 200 and may be accessible on the underside of the housing 200 where the distance checker 230 has an unobstructed line-of-sight to the ground 910. The distance checker 230 may communicate the height 320 of the housing 200 above the ground 910 to the controller 262. The height 320 of the housing 200 above the ground 910 may decrease when the cargo load is placed into the vehicle, thus indicating that the elevation angle 300 of the headlight 950 needs to be adjusted to compensate for placement of the cargo load. The height 320 of the housing 200 above the ground 910 may increase when the cargo load is removed from the vehicle, thus indicating that the elevation angle 300 of the headlight 950 needs to be adjusted to compensate for removal of the cargo load.

In some embodiments, the distance checker 230 may be a laser ranging device that directs a laser light at the ground 910 to determine the height 320. As a non-limiting example, the distance checker 230 may measure the time required for the laser light to be reflected off of the ground 910 and return to the distance checker 230 and may correlate the time with a distance.

The tilt mechanism may pivot the swivel bracket 220 responsive to an indication from the controller 262 that the height 320 of the housing 200 above the ground 910 has changed. The tilt mechanism may comprise the right motor 276, a right belt drive, the left motor 266, and a left belt drive.

The right motor 276 may convert electrical energy into mechanical energy. The right motor 276 may cause rotation of a right motor pulley 280 when electrical energy is applied to the right motor 276. The direction of the rotation may depend upon the polarity of the electrical potential that is applied by the controller 262. Rotation of the shaft of the right motor 276 in a first rotational direction 331 may cause the swivel bracket 220 to pivot in a first tilt direction 341. Rotation of the shaft of the right motor 276 in a second rotational direction 332 may cause the swivel bracket 220 to pivot in a second tilt direction 342.

In some embodiments, the right motor 276 may be a stepper motor.

The right belt drive may comprise the right motor pulley 280, a right swivel pulley 284, and a right belt 282. The right motor pulley 280 may be coupled to the shaft of the right motor 276 such that rotation of the right motor 276 causes rotation of the right motor pulley 280. The right swivel pulley 284 may be coupled to the right pivot 224 such that rotation of the right swivel pulley 284 causes rotation of the swivel bracket 220. The right motor pulley 280 may be aligned with the right swivel pulley 284 such that the right belt 282 may link the right motor pulley 280 to the right swivel pulley 284. Rotation of the right motor pulley 280 may result in rotation of the right swivel pulley 284 in the same direction. The left motor 266 may convert electrical energy into mechanical energy. The left motor 266 may cause rotation of a left motor pulley 270 when electrical energy is applied to the left motor 266. The direction of the rotation may be consistent with the direction of the pivoting caused by the right motor 276. In some embodiments, the left motor 266 may be a stepper motor.

The left belt drive may comprise the left motor pulley 270, a left swivel pulley 274, and a left belt 272. The left motor pulley 270 may be coupled to the shaft of the left motor 266 such that rotation of the left motor 266 causes rotation of the left motor pulley 270. The left swivel pulley 274 may be coupled to the left pivot 222 such that rotation of the left swivel pulley 274 causes rotation of the swivel bracket 220. The left motor pulley 270 may be aligned with the left swivel pulley 274 such that the left belt 272 may link the left motor pulley 270 to the left swivel pulley 274. Rotation of the left motor pulley 270 may result in rotation of the left swivel pulley 274 in the same direction.

The controller 262 may control the right motor 276 and the left motor 266 such that the controller 262 may change the elevation angle 300 of the headlight 950. The controller 262 may receive electrical status signals from the distance checker 230 and from the vehicle such that the controller 262 may be informed of the height 320 of the housing 200 above the ground 910, the gear that a transmission is in, the speed of the vehicle, or combinations thereof. The controller 262 may originate electrical control signals to the right motor 276 and to the left motor 266 such that the controller 262 may determine the timing and direction of rotation of the right motor 276 and the left motor 266.

Specifically, the controller 262 may read the height 320 from the distance checker 230 when the transmission is in PARK. The controller 262 may adjust the elevation angle 300 of the headlights 950 by energizing the right motor 276 and the left motor 266. In some embodiments, the controller 262 may lock the elevation angle 300 by refusing to energize the right motor 276 and the left motor 266 once the transmission is moved to any gear other than PARK. In some embodiments, the controller 262 may lock the elevation angle 300 by refusing to energize the right motor 276 and the left motor 266 if the vehicle is moving as determined by the speed of the vehicle. The controller 262 may be powered, either directly or indirectly, by a vehicle battery 902.

The headlight socket 240 may be an electrical coupling for powering the headlight 950. The headlight socket 240 may removably couple to a connector on the rear of the headlight 950.

In some embodiments, the invention 100 may comprise a switch 290. The switch 290 may be electrically coupled to the controller 262 such that the controller 262 is aware of the position of the switch 290. As non-limiting examples, the switch 290 may be accessible on the dashboard of the vehicle or placed elsewhere within the passenger compartment such that the switch 290 is accessible to the operator of the vehicle. The controller 262 may adjust the elevation angle 300 of the headlight 950 when the switch 290 is placed in a first switch position 351. The controller 262 may lock the elevation angle 300 of the headlight 950 when the switch 290 is placed in a second switch position 352.

In use, the invention 100 may be installed in the vehicle, usually in pairs. The remainder of the ‘in use’ description focuses on a single housing. When the transmission of the vehicle is placed into PARK, or when the switch 290 is placed into the first switch position 351, the controller 262 may determine the height 320 of the housing 200 by activating the distance checker 230. If the height 320 of the housing 200 has changed due to the cargo load being placed into or removed from the vehicle, the controller 262 may change the elevation angle 300 of the headlight 950. The controller 262 may rotate the right motor 276 in the first rotational direction 331 to tilt the headlight 950 in the first tilt direction 341. The controller 262 may rotate the right motor 276 in the second rotational direction 332 to tilt the headlight 950 in the second tilt direction 342. While the right motor 276 is energized, the left motor 266 may also be energized such that the right motor 276 and the left motor 266 cooperatively tilt the swivel bracket 220 in the same direction. Once the transmission is moved into a gear other than PARK, or the switch 290 is placed into the second switch position 352, the controller 262 may stop adjusting the elevation angle 300.
